1 Points to avoid

If you avoid these points you are already halfway to creating a good story.

1)Harem, this is already saturated.

2)Konoha. (Center of history).

3)Main character Uchiha/Uzumaki or who acquires his powers.

4)Protagonist get strong very fast. (10 years with hokage power.)

5)Undeveloped history, events occur very hastily.

6)Character reincarnated from our world to the naruto world. (The problem is not exactly that, but most authors do not implement anything from the protagonist's modern life for his life in the naruto world.)

7)OP System. (With shop for the protagonist to buy whatever you want and other factors we all already know.)
